gfs2: Lock holder cleanup
Make the code more readable by cleaning up the different ways of initializing lock holders and checking for initialized lock holders: mark lock holders as uninitialized by setting the holder's glock to NULL (gfs2_holder_mark_uninitialized) instead of zeroing out the entire object or using a separate flag. Recognize initialized holders by their non-NULL glock (gfs2_holder_initialized). Don't zero out holder objects which are immeditiately initialized via gfs2_holder_init or gfs2_glock_nq_init.
